PULLEY.

Specification of Letters Patent.

Patented Dec. 15, 1908.

Application led August 6, 190,8. Serial No. 447,301.

To all whom it may concern.' A

Be it known that I, JOSEPH T. MORRISON, a citizen of the United States,residing at Hartford, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inPulleys; and I do declare the following to be a full, clear, and exactdescription ofthe invention, such as will enable others skilled in theart to which it appertains to make and use the same. v

This invention has for its object the roduction of an improved clothesline pu ley provided with anti-friction means.

One of the objects of the invention is the production of a ball orroller bearing pulley aving means for guiding a rope arranged on thepulley shaft. y

Another object of this invention is the production of a ball or rollerbearing pulley provided with means for guiding a rope thereon and soarranged that the bearings may not become easily affected by moisture ofthe rope wound on said ulley.

With these and otlier objects in view, the invention consists of certalnnovel features of construction, combination and arrangement of parts, aswill be more fully described and partlcularly pointed out in theappended claims, and in the drawings in which,

Figure 1 is a side elevation of my improved clothes line pulley; Fig. 2is a horizontal sectional view taken on line 22 of Fig. 1; and Fig. 3 isa vertical sectional view taken on line 3-3 of Fig. 2.

Corresponding and like parts in the following description are indicatedin all the views by the same reference characters.

In the drawings, numeral 1 designates a pulley shaft threaded at bothends and with an Unthreaded central portion. The pulley 2 formed with aperipheral groove 3 and a central aperture 4 is mounted on the pulleyshaft 1 and the hub on said ulley is formed with an oblique aperture 5 trough which a screw 6 extends and bears against the shaft 1.

The threaded ends of the shaft 1 extend through guide plates 7 and 8.The guide plates 7 and 8 are formed substantially semicircular andprovided with outwardly facing cones 9 and 10. The guide plates 7 and 8are held spaced apart b a spacing plate 11 which is bent in the arc o aclrcle and is riveted to the edges of the guide plates 7 and 8. Thespacing plate 11 is formed with a medially disposed aperture 12 throughwhich a ring 13 is adapted to be riveted. A plurality of balls orrollers 14 are disposed in the cones 9 and 10 and a plurality of roundednuts 15 are threaded on the ends of the shaft l and bear against theballs. The ,nuts 15 are held securely on the shaft 1' by means oflocking nuts 16 which are threaded on the extremities of the shaft 1 andagainst nuts 15.

My improved clothes line pulley is suspended on a hook or line by meansof the ring 13, and a rope is passed over the pulley in the ordinarymanner. The pulley 2 is rigidly mounted on the shaft 1 and said pulleyand shaft rotate on the guide plates 7 and 8. The cones 9 and 10 of theguide plates 7 and 8 may be rovided with packing 1n the form of annu ardisks. plates 7 and 8 slightly taper from their bearing portions andeffectively prevent a rope moving over the pulley 2 from becoming wedgedagainst the sides of said pulley or from getting out of engagement withsaid pulley. The shaft l 'may be provided with a ongitudinal grooveadapted to receive the end of screw 6.

The arrangement shown in the accompanying drawings is merely forillustratlve purpose and it is understood that the exact pro ortion ofthe parts illustrated and descri ed may be changed without departingfrom the splrit of the invention. The pulley 2 is preferably formed inthe proportions shown and described which tend to produce the greatestworking efliciency.

From the fore oing description, taken in connection with t eaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extended exlanation.

Various changes in the orm, proportion andthe minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention as defined in theappended claims.

Having thus described and ascertained the nature of my invention, what Iclaim as new and desire to secure by Letters-Patent is: Y

1. A shaft formed with threaded ends, a pulley having a hub formed withan oblique aperture, a screw extending through the apeIture and bearingagainst the shaft, a plurality of bearing guide plates formed withoutwardly facing cones mounted on the shaft, a spacing plate for holdingspaced The guide apart the guide plates, balls movable on thel cones andbearing nuts threaded on the shaft against the balls.

2. A shaft formed With threaded ends, a pulley mounted on the shaft,means for securing the pulley to the shaft, a plurality of guide platesformed With outwardly facing cones, a plate for holding spaced apart theguide lates, a ring connected to the plate, balls cisposed in the conesand nuts formed With rounded ends threaded on the shaft and against theballs.

3. A shaft formed with threaded ends, a pulley secured on the shaft,semi-circular guide plates positioned on the shaft, a spaeing plate bentin the are of a circle and riveted to the edges of the guide plates, aring connected to the middle portion of the spaeing plate, ball bearingsfor the shaft and means for holding the bearings in place.

Intestiinony whereof I have hereunto set my han'd in presence of twosubscribing Witnesses.
